内蒙古达茂旗草原生态环境

Monitor on the macroscopic remote-sensing of grassland ecological environment of Da Mao United Banner in Inner Mongolia

本文在充分利用宏观遥感监测技术和地理信息系统（GIS）等先进的科技手段和方法的基础上，结合地面定位监测，运用景观生态学原理，对内蒙古达茂旗草原生态环境的现状进行了一次较全面的宏观监测。编制出了达茂旗景观生态类型图，并对该区域景观的多样性、优势度、破碎度、斑块的分布特征等宏观监测指标做了详细的分析研究。同时对达茂旗草原中沙化、砾石化、盐渍化等草原退化状况进行了重点监测研究。结果表明，达茂旗草原生态环境恶化现象已十分明显，并有继续恶化的趋势。

Based on the advanced scientific and technological tools and methods such as macroscopic remote sensing techniques and geographical informantion system, and combined the surface located minitor, the current status of the grassland ecological environment of DaMao United Banner was monitored completely, by adoping the landscape ecological theory, and the map of landscape ecological type of DaMao United Banner was drawn up. This paper analysed entirely the macroscopic monitoring indexes including diversity、 advantage、broken degree、spotted pieces and distribution feature of the regional landscape. At the same time, the degradation situation of the medium desertification、gravelation、salincation of grassland of Da Mao United Banner was monitored mainly. The result shows that the aggraved status of grassland ecological environment of Da Mao United Banner is obvious, and the trend looks serious.
